Internet of Things (IoT) based Pesticide Spraying Robot - A Revolution in Smart Farming

Abstract

Objective: To design a spraying robot based on IoT that uses less pesticide while posing fewer threats to humans and the environment. Methods: The proposed approach uses the ARM7 controller coupled with the robotic platform. Findings: A quantitative comparison with recently proposed spraying robots with our robot revealed that our robot is not only superior in range (50 m) of pesticide spreading, but it is also used less power (3.3 V only), could carry relatively huge weight (three liters), it has got optimal control navigation, and most importantly, it is economically feasible that it only needed less than USD 250 to fabricate. Novelty: Since Bluetooth controls the robot, pesticide treatments can be planned entirely through Bluetooth. In response to a precise command to the controller, the pump will turn on wherever the farmer wants to spray pesticides. The robot may be made to go forward, backward, right, left, or stop by giving it commands. Keywords: IoT; ARM 7 Controller; Bluetooth; Pesticides; Smart Farming
